1]. Claims.

This invention relates to window regulators. It has for its object a rather simple piece of mechanism for operating the two panels of the present so-called "Fisher no draft ventilator.

This Fisher no draft ventilator is one now in very common use that involves a front swinging panel which can be "cracked only slightly or which can be turned to substantially perpendicular position or even further. The panel is pivoted intermediate its front and rear edges so as to provide a greater panel area at the rear of the pivots than in front. The rear panel is slidable up and down in the window well in the usual way. This type of ventilator is described and claimed in the Alfred J. Fisher Patent No.

2,048,605 and the Edward A. Wright Reissue Patent 18,866.

This ventilator that has been heretofore used is usually provided with a conventional window regulator to raise and lower the rear window and has also been provided with a separate regulator of the crank type for swinging the front ventilator by means of a worm gear arrangement. However, some of the installations have dispensed with 5 the regulator for the front ventilating panel and have used only a friction pivot.

The present invention affords a single regulator which will first preferably disengage the rear panel from the front panel, then will open the front panel to a limited extent, say 30; further operation of the crank will lower the rear panel any desired distance or into the window well; and finally, if the rear panel has been lowered into the window well, it will again pick up the swinging panel and turn it around to perpendicular or scoop position.

In the drawing:

The figure is a view of the two panels of the Fisher no draft ventilator" and my new 49 and improved window regulator.

l designates the driving pinion which is the usual driving pinion that is utilized in window regulators in common use today. One of these window regulators is described and claimed in the Heintz and Archer Patent No. 1,655,695 and a clutch (not shown) for locking the window regulator in any given position is described and claimed in the Andersen Patent No. 1,609,281, the details of devices of this kind are not important and will not be further described. The driving pinion operates a toothed cam segment 2. This segment is a master cam that has a plurality of cam rollers that are arranged to perform the several operations outlined in the preamble.

First, the cam roller 3 engages the forked lower end of the lever 4. It throws the forked end to the left and the upper end to the right, thus throwing the slide 5 rearwardly. This slide hooks over a pin 6 on the lower end of the sash bar I a of the rear sliding window 8. This moves the rear window slightly to the rear and the front sash bar out of overlapping or sealing relation with the rear edge of the front swinging panel 9 which swings on the axis I0. 10

Thereupon, the cam 3 passes out of the notch in the forked end of the lever 4 and picks up the slide H which is provided with slots or notches l3 adapted to engage the gear teeth 14 on a shaft |5 which is attached to the lower end of 15 the ventilating panel 9. The amount of throw of the cam, the amount of travel of the slide II, and the gear ratioare such as will turn the ventilating panel about 30 and, obviously, the amount of turn could be altered by changing any 20 of the elements named. By this time, the cam roller it passes into the notch I! of the swinging regulator arm 18 and this begins to operate one of the conventional types of window regulators now used in upwardly and downwardly 25 moving window panels. Such a regulator comprises the arm l8, and a cross pivoted arm I9 that carries a roller that travels in the usual guide 20 attached to the lower end of the panel. The cross arm is also provided with a roller 2| 30 that travels in the guide 22. This stabilizes the window and prevents cocking of the window in its guides. It delivers the thrust to the window on both sides of the vertical centerline of the panel, Graf Patent No. 2,010,075. When the notch I l has been given proper angular travel, the cam roller I 6 pulls out of the notch and about this time, the cam roller 23 arrives in the end of the slot 24 and again picks up the slide II. This causes the swinging panel 9 4 'to rotate to perpendicular position, or even to a position beyond, in both of which positions air is scooped into the interior of the car.

If a division pillar be used in place of the interlocking or overlapping meeting edges of the 45 two panels afforded by'the sash bar I, then it is not necessary to use the forked lever 4 and the slide 5.

It will be noticed that the segment 25 of the window regulator arm l9 fits tightly up against 50 the cam segment. In other words, the segment 25 is convex in the same are as the cam segment 2. Hence, the cam segment can rotate with respect to the lifting arm segment 25 but, on the other hand, the lifting arm segment 25 cannot rotate 5 with respect to the cam segment 2. The cam segment 2 always holds the regulator locked against movement originating in the window or any other place except when the cam roller 16, comes around and picks up this segment when it drops into notch l1. Thereupon the notch portion 26 of the cam segment is above the pointed corner of the lifting segment 25 and affords the clearance to allow the rotation of the lifting mechanism with respect to the cam. This is a sort of Geneva movement. It is important as it provides a lock for the window lifting mechanism that it would not otherwise have except when the window lifting mechanism is coupled up with the usual clutch lock through the engagement of pin I6 in notch I'I.
